However, this selectivity comes at the cost that at the start of the implant procedure the inability of the piezoelectric devices described in these documents to impact soft tissue requires that the soft tissue covering jaw bone be reflected, i.e., cut or folded back to expose the underlying bone.

Embodiment Construction

[0017]Details regarding the design and use of piezoelectric devices are well-known in the art and are not repeated here. See, again, for example, U.S. Pat. No. 6,695,847; and U.S. Patent Publications Nos. 2007 / 0015102; 2010 / 0167235; 2010 / 0240009; and 2013 / 0045461; the entire contents of which documents are incorporated herein by reference.

[0018]Dental implants, including mini-implants, are also well-known in the art and are not detailed here. See, for example, U.S. Pat. Nos. 6,716,030; 7,112,063; 8,043,089; and 8,651,866; and U.S. Patent Publications Nos. 2005 / 0037319; 2006 / 0269903; 2006 / 0275735; 2008 / 0241791; 2012 / 0034578; and 2013 / 0101961; the entire contents of which patents and applications are incorporated herein by reference.

[0019]Cutting of soft tissues, as is known in the art, generally requires higher ultrasound vibration frequencies, for example, 50-70 kHz, preferably 50-60 kHz.

[0020]Cutting of bone, on the other hand, as is also known in the art, generally requires lower ...

Abstract

A piezoelectric device comprising:(a) a handpiece for holding by a user;(b) a cutting insert for said handpiece;(c) an ultrasound transducer disposed within the handpiece, the ultrasound transducer capable of providing first and second ultrasound frequency vibrations to the cutting insert in response to an electrical signal; and(d) a switch allowing the user to control the electrical signal and thereby provide either said first or second ultrasound frequency vibrations to the cutting insert.The device is useful in a method of placing an implant into an implant site comprising cutting overlying gingival tissue at a first ultrasound frequency capable of cutting soft tissue, then switching to a second ultrasound frequency capable of cutting the underlying jawbone.

Description

PRIORITY CLAIM[0001]The present application is a continuation of International Patent Application No. PCT / US2017 / 025895, filed Apr. 4, 2017, which claims priority of U.S. Provisional Application Ser. No. 62 / 317,688, filed Apr. 4, 2016, the entire contents of which patent applications are incorporated herein by reference.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The present invention relates to a dual function piezoelectric device.2. Description of Related Art[0003]Piezoelectric devices are known for use in dentistry, including the preparation of holes in jaw bone for placing dental implants. See, for example, U.S. Pat. No. 6,695,847; and U.S. Patent Publications Nos. 2007 / 0015102; 2010 / 0167235; 2010 / 0240009; and 2013 / 0045461; the entire contents of which documents are incorporated herein by reference. The use of piezoelectric devices, which vibrate rather than rotate, for such purposes has a number of advantages compared to conventional drills, including: (a) greater...
